Obviously, regulations and common sense are two very different things. And "public airport?" It's the difference between driving on your own driveway or ranch road and being out on the interstate. You have to do things a little differently.
I don't understand why so many people responding to this thread (and I assume they are also pilots) think it's perfectly okay to fly into a mixed use "public" airport without announcing your intentions or flying in such a way that other planes can see you. Why is that too much to ask? This particular airport is not out in Podunk Kansas. It's about 30 miles outside the Houston Mode C veil. So there's a lot of traffic out there.
What do you mean by "Podunk Kansas"?
